- to the height and width of the door .to be used in connection therewith and so that the studs and header of the door-frame need not be set to form an opening of exact size.

It has been customary heretofore in the. construction of metallic door-jambs, to con- .nect the top and sides thereof together at the factory by soldering'or riveting, or both soldering and riveting, and then forwarding thereto the building for installation. This necessitates the setting ofthe studs and header forming a door-frame to be exact,

and very often in applying a jamb so constructed to the studs and header,

- the same had to be cut away, and when iron studs were used, it was often necessary to file them to receive the jamb. Furthermore,

owing to the standard jamb being substantially in the form of connected channel bars and that the flanges thereof lie on opposite sides of the studs and headerof' a door-- frame, it has been necessary to leave one of the flanges at an obtuse angle to the web or intermediate portion in or thereby necessitating said flanges to be bent Specification 0!

My tallic invention consists of a sectional medoor-j amb formed of sheet metal fashion (1' to provide door stops and comprising. si e sections ad ust-able on the studs of the door-frame to the width required for the door, and a topsect-ion adjustable vertically on the header of the doorframe tothe height of the door.

It also consists in upper ends'of the. stop portions of theside sections to conform to the shape of the stop on the top-section so that the lattercan Joe-- placed in position first and the side sections- I Much time is therefore "lost, both at, th factory Where the jamb islace of the cutting away of the moved inward c t outward with the upper edge thereof'slidtng along the top section. By this construction, the jamb has the appearance of the ordinary metallic door jamb; there being. no visible seams and no strain is applied to any portion of the jamb. It can be quickly set into place without fitting and hammering, and without the necesportions of the door-frame, as is now often necessary.

In the drawings-Figure 1 isan elevation of a wall having a door opening with my improved jamb embodied therein and the flanges thereofcovered with a metallic casing. Fig. 2 is an enlarged vertical section taken on line 2-2, Fig. 1. Fig. 3 is an enlarged horizontalsection, taken on line 3-3, Fig. 1. Fig. 43 is a vertical section taken on line 44, of Fig. 2, the'lieader of the door frame and the top section of the jamb being broken. Fig. 5 is a perspective v1ew'of-:the 0 upper end of one of the side sections. Referring to the drawings in detail, like numerals of reference refer to like parts in .the several figures.

The reference numeral 6 designates a wall 7 a door-frame, comprising side studs 8 an a header 9.- 1 7 "Myimproved door-janib is desi ated-by tions 11 and a to tion is formed of s stantially vide a facing portion.v or web 13 and flanges 14 at right-angles to the facing portion, and

to the face of-the jamb, asat 16, thenparallel with the jamb, as at 17, and recurving the metal in ornamental fashion, as at 18. The exaet form of the stop is not essential, and various styles or forms are now employed. Inapplying these chanml shaped sections to the door. frame; the top section 12, which is cut slightly shorter-than the Width of the dooropening so that fitting is not required, is first applied to the header of the frame, and after proper adjustment vertically, it is secured in place, the flanges lying on opposite sides of the header having screw-holes through which screws 19 are passed that take into the header; but if desired, the section may be nailed in place. The manner of securing the same in place is immaterial so long as it affords the desired adj ustme'nt.

After the top section is secured to the header, the side sections 11 are applied each having the upper end of its integral stop cut-away so as to conform to the cross-sectional form of the stop on the top-section.

-The upper edges of the side sections abut against the face of the top section and'said side sections are then moved toward the side studs of the door-frame so that their flanges lie on opposite sides thereof. This permits the sides sections to be adjusted to the width of the door, and when adjusted, they are secured by screws similar to the manner rangement, the seams between the top and side sections are invisible and a neat and finished door jamb obtained which does not require preparatory fitting and can be quickly and easily adjusted to the size of the door.

Door openings of the same height but of difierent widths merely require different lengths of top sections, and as-the metal can be easily sawed to the desired lengths, at the place of installation, the many advantages of this invention will be clearly apparent.

After the jamb sections are applied, the

flanges extending over the door-frame are partly covered with metallic or other cas ings which niay be aflixed in any "approved manner. I v Having thus described my invention, what I claim is,' a

1.. The combination with a structure having an opening, of a door jambor the like By this arcomprising a top section fitting onto the header of said opening and separate side the facing-portions thereof out of contact with said frame and casings covering said flanges. v

2. A metallic jamb for door-openings orthe like comprising side sections and a top section, each section being formed of sheet metal-having its longitudinal marginal portions bentat right angles to lie on opposite,

sides of the door-frame and.having also a protruding door-stop formed integrally therewith, the upper ends of the side sections bearing against the face of the top section and having the upper ends of their stops cut away to conform to the cross-sec tional shape of the stop of the top-section,

said side sections being adjustable horizontally on said frame and said topsection being adjustable both horizontally and verti-' ca 1 3. A metallic jamb for door-openings or the like comprising a top section adapted to be secured to the header of the door-frame I and side sections adapted to be secured to the side studs. of said. frame, each section being formed of sheet-metal bent into channel formation in cross-section to provide flanges and fashioned to provide a longitudinal protruding door-stop,- the stops of the side sections being cut away at their upper.
